sPncImoAToN forming para of Letters Patent no. 476,499, dated June 7, `ieee. Application led March 14, 1892. Serial No. 424.792. (No model.)

To aZZ wil/0m it may concern:

Be it known that I, THOMAS W. TRIMBY, a citizen ofthe United States, residingat Rochester, in the -county of Monroe and State of New York, have invented certain new and useful Improvements in Shoes; and I do declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to shoes having an insole of some materialimpervious to moisture and a non-conductor of heat and cold.

The invention consists in the shoe constructed in the manner and having the features hereinafter specied and claimed.

In the accompanying drawings, Figure lis a longitudinal sectional vienT of a partiallycompleted shoe embodying my invention. Fig. 2 is a transverse section on the line ma of Fig l; Fig. 3 is a detailed view, upon an enlarged scale, of the right-hand portion of Fig. 2; and Fig. 4 is a plan view of the shoe before being turned.

lWith the construction and union of the upper and sole ofthe shoe my invention has nothing to do, said parts being las? 'fl and sewed inthe manner customary in the manufacture of turned slices, except as to the shank, as will hereinafter appear, the sewing being done either by hand or machine and by stitches that run from an inner channel on the upper side of the sole horizontally through the edge there'of and the upper.

To that side of the sole A which is the inner side in the completed shoe I attach my insole B, having .a shape conforming to that of said sole and covering the whole of the latter from toe to heel. This insole I preferably course any other material impervious to moisture and preventing the transmission of heat and cold will do. The edges of this insole are preferably skived or thinned down to avoid undue thickness or clumsiness in the finished shoe. n..

The insole B is attached to 'the sole A from the toe to the ball by any suitable adhesive substance, rubber cement, however, being preferred, and from the ball to the heel-that is, the shank portion-by means of the same and of a strip C of softupper leather, canvas, or other similar material. One of the longitudinal edges-of the strip y the upper-lining and is attached in place by being secured by the seam uniting the sole and the upper, so that the line of stitches a, that connects the latter, passes therethrough and serves also to hold it. From this point the strip is passed overand across the insole, and its other longitudinal edge is stitched to one edge of a narrow strip l) of soft leather,

canvas, or other like material, Whose other edge has previously been sewed next tothe lining of the upper in the seam uniting the upper and sole, the stitching securing these together thus serving also to hold said strip.

The strip C, attached to the shoe in the indicated mode, together with the insole, forms a shank of sullcient stiiness to make Ya sepa.-V rate shank-piece such as is commonly em ployed entirely unnecessary. The dispensing with such piece decreases the cost of manufacture of the shoe, both as to materialand labor. It decreases the Weight of the shoe and avoids the objections incidental to such piece, which arise from its becoming loose and detached from its connections in consequence of wear, causing the shoeto lose its rigidity in the shank, its propert and shape, and being asource of discomfort and annoyance to the wearer by its movements. To increase the rigidity of the shank the strip C may be attached to the insole B and Bto A .by some adhesive material, preferably fish-glue being employed, as affording great rigidity, said parts practically becoming thushomogeneous and forming a body made of sections orv layers secured together by fishglue.

The insole being -t-hus attached, as above set forth, the shoe is turned in the usual manner. After turning, in case the insole B is of cork, as the latter obviously cannot afford suliicient support for the nails used in attaching the heel, I superimpose on the heel portion of the insole a piece of thin soleleather E, con forming to the shape of the heel, into which the heel-nailscan ing through the cork and be clinched. Said heel-picee E is preferably temporarily attached to thelast by a tack or someadhesive substance before the iast is inserted for the C is placed next to! enter after pass-- IOO e evene@ second lasting, end the heel then attached to the shoe. Of course it vwill be removed from the lest with the shoe by reason of the clinching of the heel nails or tacks.

lt is oi course understood that the ordinary sock-lining is employed, and when the same is in place a perfectly even and continuons surface is eorded from the toe of the slice 'to the heel of n character not attainable Where only the-front portion of the sole is equipped with the insole. The use of the continuons insole also provides e cushion for the heel of the fooiJ and dispenses with the pocket here tofore proposed and the stitching incidental to making such pocket.

o obtain Very great rigidity in the shank l propose to insert between the sole of the shoe and the insole B e narrow scrap of sole leather or other materiel es long as the shank and united to scid parts by some adhesive materiel.

Having thus described my invention, Whatl claim to be new, and desire to secure by Letters Patent, is

A shoe provided with an insole of cork extending the length of the shoe, cemented to the sole of the same from ball to toe and secured at the shank portion by e coveringstrip C, attached to the sole at one edge by lthe lineof stitching that unites the upper andfy sole and at the other edge stitched. to :t strip.

D, that likewise is attached to the sole by the line of stitching `that unites the upper and sole and having a heel-piece E upon the heel portion of the insole to receive the heel-attaching nails or tacks, substantially es described.

In testimony whereof I afix my signature in presence of two Witnesses THOMAS W. TRIMBY.
